Real-time nucleic acid sequence-based amplification using molecular beacons for detection of enterovirus RNA in clinical specimens.
Real-time nucleic acid sequence-based amplification (NASBA) using molecular beacon technology (NASBA-beacon) was compared to standard NASBA with postamplification hybridization using electrochemiluminescently labeled probes (NASBA-ECL) for detection of enteroviruses (EV) in 133 cerebrospinal fluid and 27 stool samples. NASBA-ECL and NASBA-beacon were similar in sensitivity, detecting 55 (100%) ...
متن کاملRapid enterovirus RNA detection in clinical specimens by using nucleic acid sequence-based amplification.
Enterovirus (EV) detection by nucleic acid sequence-based amplification was compared with EV isolation in cell culture. The NucliSens Basic kit (bioMerieux) was utilized for RNA detection. For virus isolation, samples were inoculated into MRC-5, primary rhesus monkey kidney, A549, rhabdomyosarcoma, and/or Buffalo green monkey kidney cells.
متن کاملPrinciples of quantitation of viral loads using nucleic acid sequence-based amplification in combination with homogeneous detection using molecular beacons.
For quantitative NASBA-based viral load assays using homogeneous detection with molecular beacons, such as the NucliSens EasyQ HIV-1 assay, a quantitation algorithm is required. During the amplification process there is a constant growth in the concentration of amplicons to which the beacon can bind while generating a fluorescence signal. The overall fluorescence curve contains kinetic informat...
متن کاملDevelopment of conventional and real-time nucleic acid sequence-based amplification assays for detection of Chlamydophila pneumoniae in respiratory specimens.
Isothermal nucleic acid sequence-based amplification (NASBA) was applied to the detection of Chlamydophila pneumoniae 16S rRNA by using the NucliSens basic kit (bioMérieux, Boxtel, The Netherlands). The assay was originally developed as a conventional NASBA assay with electrochemiluminescence detection and was subsequently adapted to a real-time NASBA format by using a molecular beacon. C. pneu...
متن کاملSensitivity and Specificity of Nucleic Acid Sequence-Based Amplification Method for Diagnosis of Cutaneous Leishmaniasis
Abstract Background and Objective: Culture, microscopic method is a gold standard method for identification of Lishmania parasite. The use of Molecular methods such as RT- PCR compared to microscopic methods has a higher sensitivity and specificity however, it is not widely used due to its expensive equipment and the time requested. The use of nucleic acid sequence based amplification (NASBA) ...
